JOHN T. BRUEN, OF BROOKLYN, NEW YORK.

EXTENSlON-CHANDELIER.

SPECIFICATION forming part of Letters Patent No. 251,516, dated December27, 1881.

Application filed April 8, 1881. (No model.)

To all whom it may concern Beitknown that I,J oHNT.BRUEN,ofBrooklyn, inKings county, and State of New York, haveinvented certain new and usefulImprovements in Extension-Chandeliers, of which the following is aspecification.

This invention relates to that class of extension-chandeliers whereinare employed toothed racks and catches engaging therewith to retain theextensible portions of the chandeliers in different positions to whichthey may be adjusted.

My invention consists in the combination, in an extension-chandelier,with a rack on one part, of a catch on the other part, a bell-cranklever carrying said catch, and a head upon the part having said catchprovided with slots through which said lever is inserted, and thebottoms of which form stops for limiting the movement of said lever, allas hereinafter described.

It also consists in a combined guide for the toothed rack, andspringt'or actuating the catch to engage with the rack.

In the accompanying drawings, Figurel represents a sectional elevationof the'upper portion of an extension-chandelier embodying my inventionand Fig. 2 is a horizontal section of the same at the dotted line 00 m,Fig. 1.

Similar letters of reference designate corresponding parts in bothfigures.

A designates a tubular stem comprised in the lower or extensible portionof the chandelier, and B designates a toothed or indented rack, whichforms the upper or stationary portion of the chandelier. This rack isprovided at the top with a suspending-loop, a, by which it may besuspended from any fixture, and is furnished with a canopy, b, wherebythe loop is concealed and an ornamental finish imparted to the end ofthe rack. At the lower end the rack is provided with a circular head,12, fitting snuglyiu the tubular'stem and holding the said end of therack in proper position therein. At the top of the tubular stern A is aplate, 0, having an opening through which the rack passes, andconstituting a guide for the rack.

D designates a catch or tooth, which is affixed to the tubular stem, andis capable of being moved transversely tothe rack, toward and from thesame, so as to be engaged with the rack and hold the tubular stem in anydesirable position relatively to it, or to be disengaged from the rackto permit of the adjustment of the tubular stern relatively to it. Ashere shown, this catch is afiixed to one arm of an elbow or bell-cranklever, E, which is pivoted to the tubular stem A near the top, as at 19,so that the arm carrying the catch will extend downward and the otherarm laterally outward. The plate 0, which, as above explained, forms aguide for the rack B, is made ofspring metal, and extended over aprojection or third arm, 8, extending from the lever E, and thusconstitutes a spring, which, when the lever is not otherwise actuated,impels the catch D so as to engage and remain in engagement with therack. At the end of the outwardly-extending arm of the lever E isattached a roll, G, which, when pulled downward, serves to disengage thecatch from the rack to permit of the adjustment of the extensible partof the chandelier. Preferably the lever E is made, as shown, of twoplates, which pass one on each side of the rack and embrace the end of ahead, 0, of the rod G. As shown, the rod G is connected to this head 0by being screwed into the same, and hence may be disconnected therefromat pleasure. The rod G is provided at the lower end with a loop or ring,(1, whereby the rod may be pulled down by the thumb or finger of theperson seeking to adjust the extensible portion of the chandelier. Acord or chain might be used in lieu of the rod, if desirable.

1 have shown by dotted outline in Fig. 1 that the lever E might beextended in the opposite direction and a push-rod, G, substituted forthe pull-rod G, if desirable. I prefer to use the pull-rod G, however,as a pull is a more easy and natural motion to effect the disengagementof the catch from the rack, and because the hold on the rod may thenserve to prevent the extensible part from moving'upward under theinfluence of the springs which will be used to counterbalance its weightin case the person adjusting it carelessly neglects to hold itotherwise. The outwa-rdlyextending arm ofthe lever passes throughopenings or slots in a head, 0, arranged at the top of the stem A, andthe plate 0 is fastened by a screw, or otherwise, to

the head just above these slots. The bottom of the slots and theplate (3therefore form stops for limiting the motion of the lever.

It will be seen that by my invention I provide a very simple, cheap, anddesirable extensible chandelier, wherein the extensible part may beretained in position perfectly positive, the means for retainingit inposition beingsuch that there is no limitation of their retaining powerexcept the strength of the rack.

What I claim as my invention, and desire to secure by Letters Patent,is-

I. In an extension-chandelier, the combination, with a rack on one part,of a catch on the other part, the bellcranklever E, carrying said catch,and the head 0, constructed with slots for said lever, and the bottomsof which slots form stops for limiting the movement of said lever,substantially as specified.

2. In an extension-chandelier, the combination, with a rack on one part,ofa catch on the other part, a lever for actuating said catch, and aspring for actuating said catch to engage with the rack, constructed, asdescribed, to form a guide for the rack, substantially as specified.

3. In an extension-chandelier, the combination, with the rack on thestationary part, of a catch on an extensible tubular part, a lever foractuating the catch, and a spring for actuating the catch, constructed,as described, to form a combined cover for the extensible part and aguide for the rack, substantially as specified.
